OBJECTIVE To investigate the incidence and developing trends of the hospital infection among inpatients and to find out the quick path of preventing from and controlling hospital infection.METHODS Data of 188087 cases inpatients were summarized and analyzed by using the combined methods of retrospective.prospective and target monitoring.RESULTS All 5167 cases with hospital infection took place with the incidence rate of 2.75% and 6054 case-times took place with the case-times rate of 3.22%.Among the infection sites the respiratory infection ranked the first and covered 67.64%.Candida albicans was the first one among the pathogens.CONCLUSIONS Analyzing the risk factors of hospital infection and strengthening monitoring the hospital infection sources and taking measures are the important methods to prevent from and control the hospital infection.

Objective To investigate auditory sensory gating potential in the siblings of schizophrenic, to discover the neuroimaging features of sensory gating associated with schizophrenia as intermediate phenotypes. Methods Twelve siblings of schizophrenia patients in the first episodic, and 12 healthy controls matched in gender, age, education under?went MRI scan when performing a auditory sensory gating fMRI task (repeated clicks and single click auditory stimuli). The measure of sensory gating was the contrast of repeated clicks minus single click. The analysis of result was imple?mented in SPM2. Results Compared with healthy controls, schizophrenia patients showed significant overactivation in the right inter cingulate gyrus (x=4,y=8,z=32) and left anterior cingulate gyrus (x=-8,y=4,z=28) during the fMRI senso?ry gating task. Conclusion Sensory gating is overactivated in the cingulate gyrus in siblings of schizophrenic. This pat?tern may be a potential endophenotype of schizophrenia.
